This line says that you got this message via the <userlist@???>
address.

And this one via the <user1@???> address.

I've not seen you post any log lines showing your problem yet, so...

I've just setup a similar scenario to your first email:

# exim -bt userlist
userlist@??? is undeliverable: Unknown user
    <-- userlist@???
linux@???
    <-- userlist@???
  router = procmailuser, transport = procmail_delivery
rmk@???
    <-- userlist@???
  router = procmailuser, transport = procmail_delivery


What you need to do is to look in the exim main log file to find out
what's going on. You should have something like:

2008-05-05 10:08:03 1Jswfz-0002oj-8q <= linux@??? U=linux P=local S=596 id=20080505090802.GC5995@???
2008-05-05 10:08:04 1Jswfz-0002oj-8q ** userlist@???: Unknown user
2008-05-05 10:08:04 1Jswfz-0002oj-8q => rmk <userlist@???> R=procmailuser T=procmail_delivery
2008-05-05 10:08:05 1Jswfz-0002oj-8q => linux <userlist@???> R=procmailuser T=procmail_delivery
2008-05-05 10:08:06 1Jswg1-0002p5-U2 <= <> R=1Jswfz-0002oj-8q U=exim P=local S=1466
2008-05-05 10:08:06 1Jswfz-0002oj-8q Completed
2008-05-05 10:08:07 1Jswg1-0002p5-U2 => linux <linux@???> R=procmailuser T=procmail_delivery
2008-05-05 10:08:07 1Jswg1-0002p5-U2 Completed

Here, you can see linux@ sent an email to userlist@ which was expanded
to userlist@, rmk@ and linux@. The message to userlist@ failed because
no local user of that name exists.

Posting _your_ log lines corresponding to the duplicate messages will
probably show what's going on.
